Title: Katsunori Hirase: Innovator in Data Processing Technologies
Introduction
Katsunori Hirase is a prominent inventor based in Neyagawa, Japan. He has made significant contributions to the field of data processing, holding a total of 5 patents. His work focuses on innovative methods and apparatuses that enhance the efficiency of data flow and motion picture decoding.
Latest Patents
Hirase's latest patents include a data flow graph processing method and a motion picture decoding apparatus. The data flow graph processing method involves dividing a program into multiple subprograms and converting them into data flow graphs (DFGs) that represent execution dependencies. This method also generates flow data that indicates the order of execution for the DFGs. The DFGs are then transformed into configuration data, while the flow data is converted into control data.
The motion picture decoding apparatus features a coefficient reducing circuit that removes high-frequency orthogonal transform coefficients from input signals. This process reduces the number of transform coefficients by half. The apparatus also includes an inverse orthogonal transformation circuit that reconstructs image data or time-axis prediction error data. Additionally, it utilizes an adder to generate reconstructed image data based on the prediction error data and reference image data.
